Answer:
21110
Step-by-step explanation:
Pretty sure the answer is D, if you simplify it, you will have 1/5
What you need to do is multiply both sides by the same number. If 8 times 6 is 48, then 7 times 6 is your answer.
The required values are ~

I assume a unit rate is simply ms^-1 or whatever.
In order to determine m/s one must make the "per whatever" part equal to 1. In this case it is seconds, so we must make seconds equal to 1.
If in 17 seconds it travels 238 metres, that means in 1 second it travels 238/17m=14m
Therefore the unit rate (speed) of the car is 14m/s or 14ms^-1
